Douglas O38 Burd – 30in wingspan

NOTE: There is some photographic distortion in the preview at left – the plan is perfect!

Wow, another biggie!  With a 30 inch wingspan, this Burd Douglas O38 qualifies as a “Jumbo” Scale free flight rubber scale model.

With a simple and light construction, this is an excellent intermediate/advanced-level Jumbo biplane free flight flying scale model.  There’s nothing quite like the slow, graceful flight of these very large rubber powered scale models.

There are few  modifications that you’ll likely want to make in building this model.  Some wire reinforcement in the landing gear struts is a good idea and install a 1/8 inch dia alum tube rear motor peg in 1/16 x 1/2 balsa cemented behind the fuselage upright at former No-5.  A one-piece lower wing with a center section that fits into a saddle set into the lower longerons is a good idea too.   Fit a removable noseblock/noseplug assembly and a modern 10 in plastic prop with 2 loops of 3/16 Tan rubber 25 inches long to start flight trimming.  Experience the thrill of silent and majestic flight with a large stick and tissue free flight model!

Qualifies to fly in FAC Jumbo/Giant Scale events.
